LUTHER V. MOULTON AND PALMER A. JONES, OF GRAND RAPIDS, MICHIGAN.

DlPPlNG-TANK.

SPECIFICATION forming part of Letters Patent No. 621,934, dated March 28, 1899.

Application filed October 12, 1898.

To all whom it may concern:

Be it known that we, LUTHERV.1VIOULTON and PALMER A. JONES, citizens of the United States,residing at Grand Rapids,in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Dippin g-Tanks for Mixed Paints; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in dipping-tanks for mixed paints; and its object is to provide improved means for preventing the settling of the heavier particles of the paint and to provide the device with certain new and useful features, hereinafter more fully described,and particularly pointed out in the claims.

Our invention consists, essentially, in providing a horizontallyreciprocating frame within the tank and near the bottom thereof provided with a series of paddles pivoted in said frame and adapted to oscillate and present an upwardly-inclined surface to act on the liquid in the tank, and thus create upward currents therein,whereby constant circulation is maintained and the heavier particles kept uniformly distributed throughout the contents of the tank.

Referring to the accompanying drawings, Figure 1 is a side elevation of a device embodying our invention with parts broken away to show the construction; Fig. 2, a transverse vertical section of the same, and Fig. 3 a detail of the paddles.

Like letters refer to like parts in all of the figures.

A represents any suitable tank to contain the paint, preferably of sheet metal and rectangular in form. I

B are pendulum-hangers, each consisting o a single rod bent at right angles near its ends and having its ends journaled in bearings 0 near the top of the tank and at opposite sides thereof. Said rods extend downward parallel with the sides of the tank and near the same, and thence at right angles horizontally across the tank, parallel with the bottom thereof and at a suitable distance above the Serial No. 693,300. (No model.)

same, so that the agitator will traverse close to the bottom of the tank. The frame of the agitator consists of side channel-bars E, connected at a distance from each end by end channel-bars F. These bars are firmly secured to each other by means of blocks G, riveted within the ends of the bars F, and cap-screws passing through the side bars E and tapped into said blocks. The paddles I consist, preferably, of strips of sheet metal provided with longitudinal half-round grooves, in which are rods H, having their respective errds journaled at regular intervals. in suitable openings in the side bars E, the end rods beinglocated close to the end of said bars and outside the bars F to enable the end paddles to move up close to the ends of the tank. The rods H are below the middle line of the paddles, and thus the upper sides of the paddles tend to turn backward, thus at all times presenting an upwardly-inclined advancing side of the paddle. To limit the oscillation of the paddle, to strengthen the same, and to secure it upon the rod, castings J are attached to'each end of the paddles, said castings having half-round transverse recesses to fit the rod and lugs J projecting from their outer sides and embracing the side bars E. and with sufficient clearance between them to permit the paddles to automatically oscillate each way from the vertical plane to a limited extent. The frame is attached to the pendulum-hangers B by means of concave lugs D on the bars F and straps D, embracing the hangers and lugs and bolted to the latter, within which straps the hangers turn freely.

To operate the agitator, a lever K is attached to the outer end of one of the pendulum-hangers B,which lever may be operated by manual power, or preferably a shaft M, suitably journaled and provided with any convenient motive power, is provided, having a pitmanwheel N attached, from which wheel a connecting-rod L extends to the lever K to oscillate the same.

To prevent accidental contact with the agitator of the articles being dipped, a grating. is provided supported above the agitator upon brackets O. Said grating preferably consists of tubes P, with their ends resting on said brackets and connected at intervals by transverse rods Q.

\Vheu operated, the paddles reciprocate close to the bottom of the tank, and at each movement they automatically shift, so that they at all times present an upwardly-inclined advancing side to the liquid in which they move. This produces upward currents in said liquid over the field traversed by each paddle, thus maintaining a boiling action in the liquid throughout its entire mass and uniformly throughout the entire area of the tank. This effectually prevents any settling of the heavier particles.

7 Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is--- 1. The combination of a tank, a frame supported in said tank, means for reciprocating said frame, paddles pivoted in said frame and having a limited automatic oscillating movement about their pivots, whereby they present an upwardly-inclined forward surface when moving in each direction, substantially as described.

2, The combination of a tank, pendulumhangers pivoted to the sides of the tank at their upper ends, a frame pivoted to the lower ends of the hangers and supported thereby, paddles pivoted in said frame and having lugs embracing the side bars of the same and limiting the oscillation of the paddles, and means for reciprocating said frame, substantially as described.

3. The combination of a tank, a frame supported in the tank, means for reciprocating said frame, rods extending across said frame, strips of sheet metal having half-round grooves engaging the rods, and castings secured to each end of said strips, having eoneave recesses engaging said rods, and lugs on said castings embracing the side bars of the frame, substantially as described.

t. The combination of a tank having bearings in its sides near the top, rods bent at right angles near their upper ends and journaled in said bearings and extending downward within the tank and horizontally across the same, a lever attached to one of said rods,

a frame suspended below said rods by means of concave lugs on the frame and straps embracing said rods and lugs and bolted to the lugs, and paddles pivoted in said frame and having lugs near their respective corners engaging the frame and limiting the movement of said paddles, substantially as described.

5. The combination of a tank, a frame consisting of side channel-bars, and end channel-bars, blocks secured in the ends of the end bars, and cap-screws extending through the side bars and tapped into the blocks; rods extending across said frame, strips of sheet metal having half-round grooves below their middle line and engaging said rods, castings secured to the ends of said strips and having concave recesses engaging said rods, and lugs engaging the side bars of the frame, substantially as described.

6. The combination of a tank, pendulumhangers pivoted to the sides of the tank at their upper ends, a frame pivoted to thelower ends of said hangers, paddles pivoted in said frame, and having a limited automatic oscillating movement on their pivots, a lever attached to one of said hangers, a shaft having a pitman-wheel, and a connecting-rod from said wheel to the lever, substantially as described.

7. The combination of a tank, a grating in said tank, a frame beneath said grating, rods bent at right angles and journaled in the sides of the tank and extending downward beneath the grating and horizontally across the tank, a lever attached to one of said rods, a shaft and pitman-wheel, a connecting-rod from said wheel to the lever, a frame supported on said rods below the grating, paddles pivoted in said frame below their middle line and oscillating each way from a vertical plane, and lugs on said paddles engaging the side bars of the frame and limiting the oscillation of the paddles, substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
